What is happening to my Haworthia limifolia?

I think my Haworthia limifolia is either dying or self-propagating. All of a sudden this plant began to wilt and fall apart. It has a gooey looking gel inside at the bottom that was not there previously. Today we found a clump of the plant on the counter beside the container. I thought my husband had accidentally bumped it, but he did not. It is in a container with some other types of succulents. I only water a little once a week or so. In the last photo you can also see 2 of the 3 little ones that started growing several weeks back. I would greatly appreciate any help you can give me.
